E-Prime and Tobii: increasing AOIs after collecting data

I created a task using E-Prime with the Tobii extensions using a scene.  I used textboxes as areas of interest.  Unfortunately, I did not get many fixations to my AOIs or at least the textboxes were not often made apparent on my EGaze files.  Now, I need to increase my AOIs and then look through each gaze file at the XGazePos and YGazePos to see if they were looking in the new AOI parameters.  My question is about understanding the XGazePos and YGazePos in relation to the X and Y percentages on the textboxes in the GetReponse in Tobii studio.  The YGazePos seems to differ from the Y coordinate in EStudio.  Are they opposite?  For example, if I have a Y coordinate for an AOI at 15% with a height of 38%in EStudio, should I look for YGazePos numbers between .77-.93 on my egaze files?

  Nevermind, I figured it out.  They are the same.
